Answer:
Option B is correct.
The exponential function goes through the points( 1, 16) and (4 , 128) is;
Step-by-step explanation:
The general form of the exponential function is given by;
where a is the initial value and b is any value greater than 0.
If the exponential function goes through the points (1, 16) and (4, 128) we have;
16 = ab ......[1]
and
.....[2]
Divide [2] by [1] we have;
Simplify:
or
Taking cube root both sides we get;
Simplify:
b = 2
Substitute the value of b = 2 in [1] we get;
Divide both sides by 2 we get;
Simplify:
a = 8
Substitute the value of a and b in
then we have;
Therefore, the exponential function goes through the points( 1, 16) and (4 , 128) is;
